SPECIFICATION forming part of Letters Patent No. 760,741, dated ma 24, 1904.

Application filed Au ust 17,1903. Serial 110,169,694. (NomodelJl T0 at whom it may concern:

Be it known that we, WILLIAM L. KANu,'of

Pittsburg, and JAM S H. CURRY, of Wilkinsburg, in the county of Allegheny and State of Pennsylyania, have invented a certain newand'useful Fastening for Glass Plates in Store- Fronts and Show-Cases, of which thefollowing-is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which-' Figure 1 is an interior view of the meeting edges of two plates of glass, showing the inner member of our improved fastener for. securing the plates to each-other; Fig. 2 is a horizontal sectional view of the same. Fig. 3 is aside elevation of the fastener; Fig. 4 is a vertical sectional view of the outer'member of the fastener,-showing the strips for connecting it to'the inner member. Fig. 5 is a Vertical sectional viewfshowin'g the securingclip. Fig. 6 is a horizontal sectional view of a modification in which the outer member of the fastener is. in'the form offa continuous strip. Fig. 7 is a detached view. of such continuous strip. Fig. 8 is a:view'of a modification, and Fig.- 9 is a sectional view of the same. 1 s 1 1 Like symbols of reference indicate like parts in the several figures.

Our inventionrelates to an improvement in devices for securing-plates'of glass to each other, and it isespeciallyadapted for use in show-windows and show-cases.

It consists in a fastener adapted to clamp the plates of glass at any desired angle'to each other, and in such mannerthat. they shall be firmly held, forming a perfect joint, and yet so as to permit of movement of one or, the other of them, due to settling or expansion or other cause, without injury to either.:

Our improved fastener is also adapted .to be used infastening glass plates without the necessity of cutting holes in the glass. f We will now describe our invention so that others'skilled in the art may manufacture and 7 use the same.

In the drawings, 2 2 represent the twoplates of glass which it is desired to connect one with the other. In the use of our fastener the meeting edges of the-plates may be beveled, as shown'in Fig. 2,0r the plates may be united without the bevel, as shown in Figs.

6 and 8. i

The fastener itself is composed of an outer,

corner-piece 3, formed of brass, aluminium, or other metal, the leaves of which extend from each other at the angle the two plates of glass are to occupy and have a connecting,

U-shapedportion 4:, which servesas a keeper for the pintle -5, which pintle is providedwith heads 6, which may be formed by flattening the ends of the pintle and which serve to pre- -vent, the escape of the pintle from the keeper- Embracing the pintle 5 is a strip-7, of metal, preferably very thin and flexible and of a width less than the length of the pintle, which is bent around the pintle and'the'two endsof which project through'the space between the leaves of the corner-piece 3. The leaves'of the inner corner-piece 8 may be substantially of the same shapeand size as the outer cornerrpiece,andf'preferablyaremade of the same material; *biit iristead ofhaving a keeper 7 portion 4 they extend directly from .each'other at theanglefthe plates are to occupy, andzatthe apex ofthe V thus formed is afslot for the passage of the ends of the metal strip 7 "-"At theupper and lower portions of the cornerpiece8, on the innerfaces of the same and integral therewith orrigidly secured thereto, are two rings or collars-9 for passage of. the screw-bolt 10. This screw bol-tlO issl'ottedforthe passage, of the ends of the meta] 12 against movement. The outer .or' upper faceof thev upper ,collar 9 is provided" "w'i th ratchet-teeth 13, against which the head'llis adapted to bind, to prevent rotation or turning of the bolt after being brought to a fastening position.- Thebolt 1 O,,with its head 11 and nut 12, and the collars 9form a clip adapted to secure the inner corner-piece 8 on the strip 7 and against the inner faces of the plates of glass. r

In operation the meeting edges of the glass plates having been beveled, as shown in Fig. 2, the outer corner-pieces 3 are placed against the plates at their meeting edges, the thin metal strips extending between the edges of the plates. These strips are so thin as to pass between these edges without the necessity of leaving any noticeable space between the plates, or where it is desired to have strips of greater thickness the edges of the plate or plates may be filed away slightly at this point. If desired, and usually it is preferable, the corner-pieces 3 may be secured to the glass plates by means of layers of felt, cemented to the glass andto the corner-pieces by fish-glue or other suitable adhesive. A suitable number of corner-pieces 3 having been placed in position, the strips 7 extending to and beyond the inner faces of the glass plates, the inner corner-pieces 8 are passed over the strips and forced against the inner faces of the plates,

and when in this position the nuts 12 are tightened and theinner corner-pieces are locked on the strips by turning the slotted bolts 10, which wraps the thin -metal strips about the bolts and draws the corner-pieces 3 and 8 firmly against the glass, as shown in Fig. 2, thus holding the plates securely in the desired position.

As indicated in Fig. 4, the-strip 7 preferably is of a width less than the length of the pintle 5 and extends around the same, so that there may be a vertical movement of the strip on the pintle, thus permitting either or both of the glass-plates settling or expanding without breaking the glass.

In F igs. 6 and-7 we show a modification in which the outer corner-pieces 3 are formed in a continuous piece, havingat intervals strips 7, extending from the continuous pintle 5. In such case it is not necessary to bevel the meeting edges of the glass, as the outer joint of the plates is covered by the continuous cornerpiece.

In Fig. 8 we show another modification in which oneof the leaves of the outer cornerpiece is provided with an adjustable slide 14, which fits in a recess in the inner face of the leaf, being secured by the screw 15, passing through the slot 16, and it is provided with a slot 17, through which the strip 7 after making a band passes. By adjusting the slide 14 longitudinally on the' face of the leaf the slot 17 may be brought closer to or farther from the pintle 15, according to the thickness of the glass, the purpose being to permit the edges of the sheets of glass to make a butt-joint, as shown in Fig. 9, the strip 7 passing from the leaf'along the face of one-plate of glass and between this face and the edge of the other sheet. The purpose of the slide 14 is to give a fixed stationary bend to the strip 7 and to keep this bend from pressing against the edge of the glass.

The advantages of our invention will be appreciated by those skilled in the art. One of the chief advantages is thatit is not necessary to cut the glass, which not only weakens it, but formsa line of fracture in cases of unequal settling or separation of the glass. Our fastener is also very easily applied and is thoroughly efficient in securing the plates one to the other.

The corner-pieces 3 and 8 may be made to suit the angle in which it is intended that the plates shall extend, and they may be made of any size and strength desired, according to the size and thickness of the plates in connection with which they are to be used.

The flexible strips 7 allow for expansion and contraction of the glass and for settling or other movement thereof. By reason of their flexibility they may also be used where the edges of the plates are irregular.
